Description

Technical Field

[0001] The present invention relates to the technical field of building curtain walls, and in particular to an ultra-low energy consumption curtain wall structure and an installation method thereof. Background Art

[0002] In the current PC main wall insulation construction of ultra-low energy consumption projects, the handling of embedded components presents a series of pressing issues. Specifically, embedded components are typically positioned with reserved openings, combined with conventional flat embedded components for construction. After the curtain wall connectors and column keel are installed on-site, the reserved openings in the silicon graphene insulation layer must be backfilled.

[0003] The drawbacks of this traditional construction model are particularly prominent. First, the quality of the backfill is difficult to guarantee due to the lack of compatibility between the backfill material and the original silicon-graphene insulation layer. In addition, the on-site backfill operation is limited by the construction space and process precision. Problems such as incomplete filling and delamination are very likely to occur, which directly affects the integrity of the insulation system. Second, the cost is high. The backfill process not only requires additional investment in materials, labor and equipment, but the high rework and repair rate further exacerbates the cost pressure. Third, the insulation performance is impaired, and a large number of cold bridges are formed in the backfill area, resulting in increased local heat loss, which is contrary to the energy-saving requirements of ultra-low energy consumption projects. Fourth, interface cracking is frequent. The shrinkage rate and thermal conductivity of the backfill material and the silicon-graphene insulation layer differ. Under the action of temperature changes and stress, cracks are easily generated at the interface between the two, further weakening the insulation effect. Fifth, construction management is difficult. Backfill operations are often completed in high-altitude hanging baskets. Due to the limitations of the working environment, construction quality is difficult to monitor in real time. The acceptance reliability of hidden projects is low, which poses a safety hazard for later operations.

[0004] Application number: 202410483088.0, application date: 2024.022, the name of the invention is a pre-embedded structure and pre-embedded parts construction method and building for an ultra-low energy consumption building curtain wall. This invention relates to an ultra-low energy consumption building, specifically to a pre-embedded structure and pre-embedded parts construction method and building for an ultra-low energy consumption building curtain wall, including an embedded component embedded in the main concrete structure and a connecting component embedded in the exterior wall insulation layer; the embedded component includes an anchor bar and a first embedded plate, one end of the anchor bar is welded and fixed to the first surface of the first embedded plate; the connecting component includes a second embedded plate, a tooth groove and a third embedded plate, the second embedded plate is welded and fixed to the second surface of the first embedded plate through the third embedded plate, the tooth groove is welded and fixed to the inner surface of the second embedded plate, and the second embedded plate has a hole corresponding to the position of the tooth groove. Compared with the existing technology, this invention solves the problem that ordinary curtain wall embedded parts will destroy the insulation layer and form a cold bridge effect, affecting the thermal insulation performance of the exterior wall; this solution achieves effective force transmission and blocking of the cold bridge effect by designing a pre-embedded structure, and thus buildings using this pre-embedded structure can meet the requirements of ultra-low energy consumption buildings.

[0005] The above-mentioned prior art requires opening more holes and grooves in the insulation layer to accommodate the second embedded plate, the tooth groove and the third embedded plate, and requires relying on thermal insulation gaskets to block cold bridges. Summary of the Invention

[0006] In view of the defects of the above-mentioned existing technology such as destroying the overall continuity of the insulation layer and relying on the later manual installation of insulation gaskets to block cold bridges, the purpose of the present invention is to provide an ultra-low energy consumption curtain wall structure and its installation method with less damage to the insulation layer and a small cold bridge cross-section.

[0007] The technical solution provided by the present invention is:

[0008] An ultra-low energy consumption curtain wall structure, comprising:

[0009] An embedded part, comprising a steel plate, a sleeve, and an anchoring rib; the steel plate has a first surface and a second surface disposed opposite to each other along a thickness direction, the sleeve is fixedly connected to the first surface, and the anchoring rib is fixedly connected to the second surface;

[0010] The sleeve member includes a plurality of sleeve bodies, and the anchoring bars are used for anchoring with concrete;

[0011] The thermal insulation layer is provided with a plurality of through holes for the sleeve body to pass through, and the inner diameter of the through holes is adapted to the outer diameter of the sleeve body;

[0012] A curtain wall connector is installed on a side of the insulation layer relatively away from the steel plate through a first fastening component, and the first fastening component is detachably connected to the sleeve body; the curtain wall connector is used to connect to the curtain wall column.

[0013] Furthermore, the sleeve body and the anchoring ribs are perpendicular to the steel plate;

[0014] When the sleeve body is inserted into the through hole, the inner surface of the thermal insulation layer is in contact with the steel plate, and the end of the sleeve body relatively away from the steel plate is flush with the outer surface of the thermal insulation layer.

[0015] Furthermore, a strip-shaped sliding groove with closed ends is provided on the curtain wall connector at a position corresponding to the through hole, and the first fastening component passes through the strip-shaped sliding groove and is connected to the sleeve body;

[0016] The strip-shaped slide groove is used to enable the curtain wall connecting member to move horizontally relative to the first fastening assembly.

[0017] Furthermore, the curtain wall connector includes:

[0018] A fixed plate, the strip-shaped slide groove is provided on the fixed plate, and the strip-shaped slide groove extends to both sides of the through hole;

[0019] The cantilever plate is fixedly connected to the fixed plate; the curtain wall column is installed on the cantilever plate through a second fastening assembly.

[0020] Furthermore, a transverse sliding groove is provided on the cantilever plate, one end of the transverse sliding groove is relatively close to the fixed plate, and the other end is relatively far away from the fixed plate;

[0021] The second fastening assembly is connected to the curtain wall column through the transverse sliding groove, and the curtain wall column can drive the second fastening assembly to move along the transverse sliding groove, so that the curtain wall column is relatively close to or away from the fixing plate.

[0022] Furthermore, the fixing plate has a third surface and a fourth surface that are oppositely arranged along the thickness direction thereof;

[0023] The third surface is in contact with the outer surface of the thermal insulation layer, the fourth surface is provided with a first concave-convex surface around the strip-shaped slide groove, and the first fastening component includes a second concave-convex surface adapted to the first concave-convex surface;

[0024] Furthermore, the cantilever plate has a fifth surface and a sixth surface arranged opposite to each other along the thickness direction thereof;

[0025] The fifth surface is in contact with the curtain wall column, the sixth surface is provided with a third concave-convex surface around the transverse sliding groove, and the second fastening component includes a fourth concave-convex surface adapted to the third concave-convex surface.

[0026] Furthermore, the sleeve member further comprises a reinforcing rib fixedly connected to the sleeve body, and along the axial direction of the sleeve body, the height of the reinforcing rib is smaller than the height of the sleeve body;

[0027] One end of the reinforcing rib is fixedly connected to the first surface of the steel plate, and the other end is lower than the end of the sleeve body away from the steel plate.

[0028] Furthermore, the ratio of the height of the reinforcing rib to the height of the sleeve body is 2 / 3 to 3 / 4.

[0029] Furthermore, the thermal insulation layer is provided with grooves for accommodating reinforcing ribs, and the grooves do not penetrate the thermal insulation layer.

[0030] A method for installing an ultra-low energy consumption curtain wall structure comprises the following steps:

[0031] S1: Welding a reinforcing rib to a sleeve body to form a sleeve member, wherein the height of the reinforcing rib is smaller than the height of the sleeve body, and one end of the reinforcing rib is flush with one end of the sleeve body;

[0032] The steel plate has a first surface and a second surface facing each other along its thickness direction. The sleeve body and the end flush with the reinforcing rib are simultaneously fixedly connected to the first surface of the steel plate, and the anchor bar is fixedly connected to the second surface of the steel plate. The above steps are repeated to form a plurality of embedded parts including sleeve parts, steel plates and anchor bars.

[0033] S2: The insulation layer is drilled in the factory. The drilled slots include through holes corresponding to the sleeve body and grooves corresponding to the reinforcing ribs. Along the thickness direction of the insulation layer, the through holes penetrate the insulation layer, while the grooves do not penetrate the insulation layer.

[0034] S3: Insert the sleeve into the through hole and groove accordingly, so that after the sleeve body passes through the through hole, the inner surface of the insulation layer is in contact with the steel plate; the outer surface of the insulation layer at the end of the sleeve body away from the steel plate is flush;

[0035] S4: After the insulation layer and embedded parts are arranged in order, concrete is poured and cured in the factory. The concrete is bonded to the anchor bars, so that the insulation layer and embedded parts are integrated with the concrete. The above operation is repeated to form several integrated parts consisting of embedded parts, insulation layer and concrete.

[0036] S5: transport several pre-buried parts, insulation layer and concrete to the site and hoist them to the building facade;

[0037] Filling the gap between the sleeve body and the through hole with a sealing member;

[0038] Connecting the curtain wall connector to the embedded part through the first fastening assembly;

[0039] Perform mortar finishing operations on the outer surface of the insulation layer to form a mortar layer;

[0040] The curtain wall columns are installed on the curtain wall connectors through the second fastening assembly.

[0041] Furthermore, in step S2, the insulation layer is punched using a template;

[0042] The template is pre-opened with through holes corresponding to the through holes and grooves. After the template is attached to the location of the insulation layer where the holes are to be opened and fixed, a hole punch is used to punch through the insulation layer, and a customized saw blade is used to cut grooves to accommodate the reinforcing ribs.

[0043] Furthermore, in step S4, before pouring concrete, a plug is inserted into the end of the sleeve body away from the steel plate to prevent concrete from leaking into the open end of the sleeve body.

[0044] Furthermore, in step S5, the curtain wall connector includes a fixing plate connected to the embedded part and a cantilever plate cantilevered from the fixing plate;

[0045] A strip-shaped slide groove is provided on the fixing plate, and the strip-shaped slide groove is used to enable the curtain wall connector to move horizontally relative to the first fastening component to adjust the position of the curtain wall connector;

[0046] A transverse slide is provided on the cantilever plate, one end of the transverse slide is relatively close to the fixed plate, and the other end is relatively far away from the fixed plate; the transverse slide is used to enable the curtain wall column to be relatively close to or away from the fixed plate to achieve adjustment of the position of the curtain wall column.

[0047] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0048] (1) The present invention forms the embedded parts, insulation layer, and concrete in one step at a PC factory (precast concrete component factory), thereby significantly reducing the number of through holes and grooves between the insulation layer and the sleeve. Furthermore, the grooves do not penetrate the outer surface of the insulation layer, significantly reducing the degree of damage to the insulation layer. This integrated molding method not only avoids the problem of irregular gaps caused by on-site cutting, but also ensures the uniformity and airtightness of the gaps, fundamentally reducing the possibility of the cold bridge effect and meeting the stringent insulation performance requirements of ultra-low energy consumption buildings.

[0049] (2) The present invention has high efficiency in opening holes and slotting: the installation of traditional ultra-low energy embedded parts involves multiple on-site operation processes, and all operations are carried out in a high-altitude hanging basket, which easily leads to the situation of opening beyond the scope of the hole. In addition, the insulation is divided into two parts and backfilled, resulting in an incomplete insulation layer that is easy to fall off and poor construction quality. The present invention does not require on-site insulation backfilling, and no welding work is required on-site when the connectors are fixed. The working conditions for opening round holes and slots in the PC factory are good, and the efficiency of opening holes and slotting is high.

[0050] (3) The connectors of the present invention do not require welding: In traditional connection structures, the weld length between the connectors and embedded parts reaches 0.52m, and the position cannot be adjusted after welding. There is a lot of welding work involved, and three-dimensional adjustment is not possible after welding. In addition, after welding, it is necessary to remove the welding slag and apply two coats of anti-rust paint, resulting in a huge workload for on-site construction. The connectors of the present invention are connected to the embedded parts by bolts, eliminating the need for welding, greatly improving construction efficiency, and three-dimensional adjustment can still be performed after the keel is installed.

[0073] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments.

They are not used to limit the conditions for implementation of the present invention and therefore have no substantial technical significance.

At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of implementation. Changes or adjustments in their relative relationships should also be considered as the scope of implementation of the present invention without substantially changing the technical content.

[0075] An ultra-low energy consumption project refers to a building project that significantly reduces energy consumption throughout the building's entire life cycle by adopting high-efficiency energy-saving technologies, materials and equipment, combined with optimized building design and operation and maintenance management, while achieving a comfortable indoor environment and environmentally friendly environment.

[0076] For example, by optimizing the building orientation, enhancing the thermal insulation performance of the enclosing structure, improving the airtightness of doors and windows, etc., the dependence on active heating and cooling systems can be minimized; the building energy consumption level can be much lower than that of conventional buildings, and generally can meet the higher requirements of the current national or local energy-saving standards, focusing on energy saving while ensuring the health and comfort experience of residents.

[0077] In ultra-low energy projects, PC main wall insulation construction refers to factory-prefabricated concrete wall components. These components are processed in the factory and then transported to the construction site for assembly and installation, making them a crucial component of prefabricated buildings. While using PC main wall cladding in ultra-low energy projects can improve construction efficiency and ensure component quality, it also places higher demands on supporting construction elements such as insulation and embedded components.

[0078] The ultra-low energy consumption curtain wall structure of this application adopts PC main wall construction, and at the same time optimizes the design of the insulation layer and embedded parts, which fundamentally solves many pain points of the traditional construction mode: the curtain wall structure does not require subsequent backfilling operations during the construction process, which not only greatly reduces the cold bridge cross-section, but also maximizes the integrity of the insulation layer, avoids secondary damage to the insulation layer due to backfilling, and effectively ensures the continuity of the insulation system.

[0079] Example 1

[0080] The present application discloses an ultra-low energy consumption curtain wall structure, comprising embedded parts 1, an insulation layer 2, curtain wall connectors 3 and concrete 4.

[0081] The embedded part 1 includes a steel plate 11 , a sleeve part 12 and an anchoring bar 13 . When the concrete 4 is poured in the factory, the anchoring bar 13 is used to be anchored and connected with the concrete 4 .

[0082] The steel plate 11 includes a first surface and a second surface opposite to each other along its thickness direction. The sleeve 12 is fixedly connected to the first surface, and the anchor rib 13 is fixedly connected to the second surface. The sleeve 12 and the anchor rib 13 are perpendicular to the steel plate 11.

[0083] In order to ensure the connection strength and structural stability, the fixed connection method is preferably welding. Through welding, the sleeve member 12, the anchor bar 13 and the steel plate 11 can form a solid whole, which can effectively resist the external force during construction and use.

[0084] In addition to welding, the sleeve 12 and the steel plate 11, and the anchor ribs 13 and the steel plate 11, can also be connected by bolts. Specifically, threaded holes can be pre-formed at corresponding locations on the steel plate 11, and matching external threads can be provided at the connecting ends of the sleeve 12 and the anchor ribs 13. These threads engage to secure the sleeve 12 and the anchor ribs 13 to the steel plate 11. This method offers the advantage of ease of disassembly and replacement, allowing for quick and easy repair and replacement if components become damaged.

[0085] Alternatively, riveting can be used. Rivets are inserted through prefabricated holes in the sleeve 12, anchor rib 13, and steel plate 11. External force causes the rivets to plastically deform, tightly connecting the three. Riveting is simple to operate and offers stable connection strength, making it suitable for thin steel plates. It ensures connection reliability while minimizing damage to the steel plate structure, and the construction process is relatively safe.

[0086] The sleeve member 12 includes a plurality of sleeve bodies 121 and reinforcing ribs 122 fixedly connected to the sleeve bodies 121. One end of the sleeve body 121 away from the steel plate 11 is open, and the open end is used for the subsequent insertion of the first fastening assembly 5.

[0087] It is worth noting that before pouring concrete 4 in the factory, the plug 25 is inserted into the open end of the sleeve body 121 to prevent the concrete 4 from leaking into the sleeve body 121. When the curtain wall connector 3 is subsequently installed, the plug 25 is pulled out.

[0088] Along the axial direction of the sleeve body 121, the height of the reinforcing rib 122 is less than the height of the sleeve body 121. More specifically, the height ratio of the reinforcing rib 122 to the height of the sleeve body 121 is in the range of 2 / 3 to 3 / 4.

[0089] One end of the reinforcing rib 122 is flush with the end of the sleeve body 121 close to the steel plate 11, ensuring that the two can be synchronously and firmly connected to the steel plate 11 and bear the force together; and the other end of the reinforcing rib 122 is significantly lower than the open end of the sleeve body 121 away from the steel plate 11.

[0090] The insulation layer 2 is provided with a through hole 21 for the sleeve body 121 to pass through. The inner diameter of the through hole 21 matches the outer diameter of the sleeve body 121. Furthermore, the insulation layer 2 is provided with a groove 22 for accommodating the reinforcing rib 122. It is worth noting that the through hole 21 passes through the insulation layer 2, while the groove 22 does not.

[0091] This design of openings and slots is closely related to the concept of ultra-low energy consumption. It reduces the structural damage of the insulation layer 2 and ensures the continuity of the insulation layer, thereby reducing the energy loss caused by the cold bridge effect. At the same time, it avoids the quality problems that may be caused by backfilling in the later stage, reduces the thermal bridge effect and installation stress of the curtain wall structure, and achieves ultra-low energy consumption.

[0092] It is worth noting that the outer surface of the thermal insulation layer 2 is the side facing the curtain wall connector 3 , and the inner surface of the thermal insulation layer 2 is the side facing the steel plate 11 .

[0093] When the sleeve body 121 passes through the through hole 21 , the inner surface of the insulation layer 2 is in contact with the steel plate 11 , and the end of the sleeve body 121 farther from the steel plate 11 is flush with the outer surface of the insulation layer 2 .

[0094] The sleeve body 121 and the reinforcing ribs 122 can be combined in various forms to form sleeve members 12 with different structures, so as to adapt to the force requirements in different scenarios.

[0095] For example, the sleeve member 12 can adopt a double-sleeve combination structure, specifically including two sleeve bodies 121 and a reinforcing rib 122 located between the two sleeve bodies 121. The upper and lower sides of the reinforcing rib 122 are respectively welded and fixed to the outer walls of the two sleeve bodies 121 to form an "I"-shaped force-bearing unit.

[0096] The advantage of this structure is that the middle reinforcing rib 122 effectively enhances the connection stiffness between the two sleeve bodies 121, so that the two form a force-bearing whole and jointly resist the horizontal shear force. It is particularly suitable for ultra-low energy consumption project scenarios with large curtain wall loads and high requirements for structural deformation resistance, ensuring the mechanical stability of the overall structure and complying with the design principle of giving equal importance to energy saving and safety.

[0097] For another example, the sleeve member 12 can adopt a single-sleeve, multi-rib combination, specifically comprising a sleeve body 121 and multiple reinforcing ribs 122 evenly distributed along the circumference of the sleeve body 121. One side of each reinforcing rib 122 is fixedly connected to the outer wall of the sleeve body 121. This structural design has significant advantages: the evenly distributed reinforcing ribs 122 can support the sleeve body 121 from multiple directions, significantly enhancing the torsional resistance and radial rigidity of the sleeve body 121.

[0098] Furthermore, since each sleeve member 12 is provided with only one sleeve body 121, the number of through-holes 21 required in the corresponding insulation layer 2 is minimized, minimizing damage to the overall structure of the insulation layer 2 and better meeting the stringent insulation integrity requirements of ultra-low energy buildings. This is particularly suitable for ultra-low energy projects with high requirements for insulation continuity and complex force directions.

[0099] After the insulation layer 2, along with the embedded components 1 and concrete 4, is transported to the construction site and hoisted onto the building facade, the curtain wall connectors 3 and embedded components 1 are installed, and the outer surface of the insulation layer 2 is mortared to form a mortar layer 8 with a thickness of 5 mm to 15 mm. The insulation layer 2 preferably uses silicon graphene as the insulation material.

[0100] Mortar finishing can protect the insulation layer 2. Mortar finishing can form a hard protective layer that can resist the erosion of the insulation material by wind, rain, dust and other external environments, thereby extending the service life of the insulation layer.

[0101] In addition, mortar finishing can form a relatively dense interface on the outer surface of the insulation layer, reduce air infiltration, and further improve the thermal insulation performance of the insulation layer, meeting the energy-saving performance requirements of ultra-low energy consumption buildings, while also providing convenient conditions for subsequent waterproofing treatments and other processes.

[0102] The curtain wall connector 3 is installed on the side of the insulation layer 2 relatively far from the steel plate 11, that is, it is attached to the outer surface of the insulation layer 2. The curtain wall connector 3 is fixedly connected to the embedded component 1 through the first fastening component 5. Specifically, the first fastening component 5 passes through the opening of the curtain wall connector 3 and then into the open end of the sleeve body 121, forming a detachable connection with the sleeve body 121.

[0103] The setting of the curtain wall connector 3 provides stable support for the subsequent curtain wall installation. After the curtain wall connector 3 is fixed, the curtain wall column 6 can be installed on the curtain wall connector 3 to ensure that a reliable force transmission path is formed between the curtain wall structure and the main structure.

[0104] At the same time, since the curtain wall connector 3 is directly attached to the outer surface of the insulation layer 2 and is tightly connected to the sleeve body 121 through the first fastening component 5, the cold bridge points caused by additional connecting components can be reduced, further conforming to the energy-saving design concept of ultra-low energy consumption buildings.

[0105] In addition, this installation method does not require additional drilling or welding operations on the outer surface of the insulation layer 2, which can preserve the integrity of the insulation layer 2 to the greatest extent and reduce the adverse effects of construction operations on the insulation performance.

[0106] Furthermore, the curtain wall connector 3 includes a fixed plate 32 and a cantilever plate 33 , which are fixedly connected and preferably formed in one piece.

[0107] The fixing plate 32 fits in contact with the outer surface of the insulation layer 2; a strip-shaped slide groove 31 with closed ends is provided at a position corresponding to the through hole 21 on the fixing plate 32, and the strip-shaped slide groove 31 extends to both sides of the through hole 21. The length of the strip-shaped slide groove 31 is greater than the inner diameter of the through hole 21. The first fastening component 5 passes through the strip-shaped slide groove 31 and is connected to the sleeve body 121.

[0108] Through the structural design of the strip-shaped slide groove 31, the curtain wall connector 3 can be moved horizontally relative to the first fastening component 5, thereby meeting the need for fine-tuning the position of the curtain wall connector during installation.

[0109] The cantilever plate 33 cantilevers outward and is provided with a transverse sliding groove 34 . One end of the transverse sliding groove 34 is relatively close to the fixed plate 32 , while the other end is relatively far away from the fixed plate 32 .

[0110] The second fastening assembly passes through the transverse slot 34 and is connected to the curtain wall column 6. The curtain wall column 6 can drive the second fastening assembly to move along the length direction of the transverse slot 34, thereby achieving the fine-tuning requirement of the curtain wall column 6 in the spatial position.

[0111] In order to enhance the stability of the curtain wall connector 3 and the curtain wall column 6 after fine-tuning and avoid their random displacement, a concave-convex surface is provided on the curtain wall connector 3, and the first fastening component 5 and the second fastening component are both provided with a concave-convex surface adapted thereto.

[0112] Specifically, the fixing plate 32 has a third surface and a fourth surface that are oppositely arranged along its thickness direction; wherein the third surface is in contact with the outer surface of the insulation layer 2 , and the fourth surface is provided with a first concave-convex surface 321 around the strip-shaped slide groove 31 .

[0113] The first fastening assembly 5 includes a first bolt 51 and a first stopper plate 52. The sleeve body 121 preferably has internal threads, and the first bolt 51 has external threads that match the internal threads of the sleeve body 121. The first stopper plate 52 has a through hole for the first bolt 51 to pass through. The first stopper plate 52 covers the strip-shaped slide groove 31 and is disposed opposite the fourth surface of the fixing plate 32. The side of the first stopper plate 52 opposite the fourth surface has a second concave-convex surface that matches the first concave-convex surface 321.

[0114] The cantilever plate 33 has a fifth surface and a sixth surface disposed opposite to each other along its thickness direction; wherein the fifth surface is in contact with the curtain wall column, and the sixth surface has a third concave-convex surface 331 around the transverse slide groove 34 .

[0115] The second fastening assembly includes a second bolt 71 and a second limiting plate 72; a through hole for the second bolt 71 to pass through is opened on the second limiting plate 72, the second limiting plate 72 covers the horizontal slide groove 34, and the second limiting plate 72 is arranged opposite to the sixth surface of the cantilever plate 33, and the side of the second limiting plate 72 opposite to the sixth surface is provided with a fourth concave-convex surface adapted to the third concave-convex surface 331.

[0116] The four concave-convex surfaces are preferably sawtooth-shaped. Alternatively, the concave-convex surface can be wavy. Both shapes achieve meshing through a continuous undulating structure.

[0117] Example 2

[0118] The present invention provides an installation method for an ultra-low energy consumption curtain wall structure, comprising the following steps:

[0119] S1: Welding the reinforcing rib 122 to the sleeve body 121 to form the sleeve member 12, wherein the height of the reinforcing rib 122 is smaller than the height of the sleeve body 121, and one end of the reinforcing rib 122 is flush with one end of the sleeve body 121;

[0120] The steel plate 11 has a first surface and a second surface facing each other along its thickness direction. The sleeve body 121 and the flush ends of the reinforcing ribs 122 are simultaneously welded to the first surface of the steel plate 11, and the anchoring ribs 13 are welded to the second surface of the steel plate 11. The above steps are repeated to form a plurality of embedded parts 1 including the sleeve member 12, the steel plate 11, and the anchoring ribs 13.

[0121] S2: The thermal insulation layer 2 is drilled in the factory, i.e., a through hole 21 corresponding to the sleeve body 121 is formed in the thermal insulation layer 2, and a groove 22 corresponding to the reinforcing rib 122 is formed. Along the thickness direction of the thermal insulation layer 2, the through hole 21 penetrates the thermal insulation layer 2, while the groove 22 does not penetrate the thermal insulation layer 2.

[0122] S3: Insert the sleeve 12 into the through hole 21 and the groove 22 one by one, so that after the sleeve body 121 passes through the through hole 21, the inner surface of the insulation layer 2 is in contact with the steel plate 11, and the end of the sleeve body 121 away from the steel plate 11 is flush with the outer surface of the insulation layer 2;

[0123] S4: After the insulation layer 2 and the embedded parts 1 are arranged in order, concrete 4 is poured and cured in the factory. The concrete 4 is bonded to the anchor bars 13, so that the insulation layer 2 and the embedded parts 1 are integrated with the concrete 4.

[0124] Repeat the above operation to form several integral parts consisting of embedded parts 1, insulation layer 2 and concrete 4;

[0125] S5: transporting several integrated embedded parts 1, insulation layer 2 and concrete 4 to the site and hoisting them to the building facade;

[0126] Fill the gap between the sleeve body 121 and the through hole 21 with a sealing member 24;

[0127] Then, the curtain wall connector 3 is connected to the embedded part 1 through the first fastening assembly 5, and mortar finishing is performed on the outer surface of the insulation layer 2 to form a mortar layer 8;

[0128] Finally, the curtain wall column 6 is installed on the curtain wall connector 3 through the second fastening assembly.

[0129] It is worth noting that, in step S2, the insulating layer 2 is punched with a template 23;

[0130] The master form 23 is pre-opened with through holes corresponding to the through holes 21 and the grooves 22. After the master form 23 is attached to the location where the holes are to be opened in the insulation layer 2 and fixed, a hole punch is used to punch through the insulation layer to form the through holes 21, and a customized saw blade is used to cut grooves to form the grooves 22 for accommodating the reinforcing ribs.

[0131] In step S4 , before pouring the concrete 4 , the plug 25 is inserted into the end of the sleeve body 121 away from the steel plate 11 to prevent the concrete 4 from leaking into the open end of the sleeve body 121 .

[0132] In step S5, the curtain wall connector 3 includes a fixing plate 32 connected to the embedded part 1 and a cantilevered plate 33 cantilevered from the fixing plate 32;

[0133] A strip-shaped slide groove 31 is provided on the fixing plate 32. The strip-shaped slide groove 31 is used to enable the curtain wall connector 3 to move horizontally relative to the first fastening assembly 5, so as to adjust the position of the curtain wall connector 3.

[0134] A transverse sliding groove 34 is provided on the cantilever plate 33 , one end of the transverse sliding groove 34 is relatively close to the fixed plate 32 , and the other end is relatively far away from the fixed plate 32 ; the transverse sliding groove 34 is used to enable the curtain wall column 6 to be relatively close to or away from the fixed plate 32 to achieve adjustment of the position of the curtain wall column 6 .

[0135] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
